 | Asteroids with moons, which scientists call binary asteroids, are common in the solar system. A longstanding question has been how the majority of such moons are formed. A trio of astronomers from Maryland and France say the surprising answer is sunlight, which can increase or decrease the spin rate of an asteroid. ...> Full Article |
 | The dramatic differences between the northern and southern hemispheres of Mars have puzzled scientists for 30 years. One of the proposed explanations--a massive asteroid impact--now has strong support from computer simulations carried out by two groups of researchers ...> Full Article |

 | Graduate student Cristina Thomas has been making observations of asteroids using a large NASA telescope in Hawaii, at least once a month for more than three years now. Doing this kind of astronomical research has traditionally required a lot of time and money for travel, but Thomas usually can get to the telescope just by walking down the hall. ...> Full Article |
Using visible and infrared data collected from telescopes on Hawaii's Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects.

University of Virginia research scientist Greg Black, working with astronomers at NASA and other institutions, has captured images of a small asteroid that passed relatively close to Earth on Jan. 29. Astronomers are busily refining their techniques for locating and observing asteroids that could potentially be a threat to our planet.

 | Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials. ...> Full Article |
 | The Arecibo Observatory in Arecibo, Puerto Rico will observe a newly discovered asteroid on Jan. 27-28, as the object called 2007 TU24 passes within 1.4 lunar distances, or 334,000 miles, from Earth. ...> Full Article |
 | Scientists are monitoring the orbit of asteroid 2007 TU24. The asteroid, believed to be between 150 meters (500 feet) and 610 meters (2,000 feet) in size, is expected to fly past Earth on Jan. 29, with its closest distance being about 537,500 kilometers (334,000 miles) at 12:33 a.m. Pacific time (3:33 a.m. Eastern time). It should be observable that night by amateur astronomers with modest-sized telescopes. ...> Full Article |
New Mexico Tech's Magdalena Ridge Observatory (MRO) is already making its mark in the annals of astronomy research after being recently tasked by NASA to make detailed observations of an asteroid that is now given a 1 in 75 chance of hitting Mars on January 30, 2008.

 | Hollywood thrillers such as "Deep Impact" helped to jump-start America's interest in knowing what our "deflection strategy" would be if a giant asteroid was on a potentially catastrophic collision course with Earth. ...> Full Article |
UC Davis physics professor J. Anthony Tyson will testify before Congress on Thursday, Nov. 8, on near-Earth asteroids. Tyson will talk about the potential role of the proposed Large Synoptic Survey Telescope (LSST) in surveying the sky for objects that might eventually strike our planet. The hearing of the House Committee on Science and Technology will begin at 10 a.m. in room 2318 of the Rayburn Office Building.

 | Echoing the re-discovery of America by the Spanish long after an earlier Viking reconnaissance, astronomers have learned that a recently observed asteroid - one that could potentially hit the Earth - was actually first observed nearly a half-century ago. Researchers at the Minor Planet Center of the Smithsonian Astrophysical Observatory in Cambridge, MA have confirmed work by SETI Institute astronomer Peter Jenniskens that the recently discovered asteroid 2007 RR9 is in fact the long-lost object 6344 P-L. ...> Full Article |
Undergraduate astronomy students at the University of Washington combing through images from a specialized telescope have discovered more than 1,300 asteroids that had never before been observed. That is about one out of every 250 known objects in the solar system.

 | Every now and then a space rock hits the world's media - sometimes almost literally. Threatening asteroids that zoom past the Earth, fireballs in the sky seen by hundreds of people and mysterious craters which may have been caused by impacting meteorites; all make ESA's studies on the Don Quijote mission look increasingly timely. ...> Full Article |
 | The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 65 million years ago has been traced back to a breakup event in the main asteroid belt. A joint U.S.-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague suggests that the parent object of asteroid (298) Baptistina disrupted when it was hit by another large asteroid, creating numerous large fragments that would later create the Chicxulub crater on the Yucatan Peninsula as well as the prominent Tycho crater found on the Moon. ...> Full Article |
 | The traditional belief that Jupiter acts as a celestial shield, deflecting asteroids and comets away from the inner Solar System, has been challenged by the first in a series of studies evaluating the impact risk to the Earth posed by different groups of object. ...> Full Article |
